You can find additional examples and documentation on the dygraphs for R website.

Bringing JavaScript to R

One of the reasons we are excited about dygraphs is that it takes a mature and feature rich visualization library formerly only accessible to web developers and makes it available to all R users.

This is part of a larger trend enabled by the htmlwidgets package, and we expect that more and more libraries like dygraphs will emerge over the coming months to bring the best of JavaScript data visualization to R.
